2.3 Signing Display and Event Data
You can sign display and event data from the historical trend display.
You can sign a unit of data when:
• You are logged in as a user with signature privileges.
• The files are in the internal memory (even if the data is in the internal memory, you
cannot sign it unless it has been saved to files).
• The data has not already been signed in the same place.
• The DX settings allow signing.
• All the data that you want to sign can be displayed.
For example, the DX can display up to 1000 alarms. You cannot sign a file that has more than
1000 alarms. To sign such a file, use DAQSTANDARD.
For the setting procedure, see “Signature > Sign from recorder” on page 2-7.
• When Process type is set to Batch, the measured data from memory start to memory
stop is contained in one file.
